Abstract
The selective acetalization of a sugar and an alcohol is carried out using zeolite and zeotype catalysts of medium and large pore size with rings containing 10 members or more having acid properties. The sugars used are monosaccharides or disaccharides or mixtures of these, of the type known as reducing sugars. The alcohols contain between 1 and 25 carbons, preferably straight chain primary alcohols.
